While it might be apple picking season, I love that apples are a year-round fruit that I can use for baking! Just like my apple pie cinnamon rolls, this apple oat crumble pie is loaded up with apple flavor!

Also known as a Dutch apple pie or apple crumb pie, this pie has a filling of sweet cinnamon apples that is topped with a crunchy oat streusel. I've baked it in my favorite flaky crust recipe but you can use a store-bought pie crust too!

What I love about an apple crumble pie recipe is how easy it is. No fussy lattice to worry about and it's so simple to make. If you want a mini version of this pie, check out my mini apple pies with puff pastry!

Why you'll love this recipe!

Perfect Pie: This pie has a sweet apple pie filling with a spiced crumb topping. Truly the perfect pie for Fall, Thanksgiving or the holiday season!
Pantry Ingredients: I'm using simple pantry ingredients here, nothing too fancy.
Pie Crust: You can make my homemade pie crust recipe but you can also buy a ready-made one at the store if you're low on time.
Serve with Ice Cream: Is perfect served with a giant scoop of vanilla ice cream and salted caramel sauce!

Ingredients Needed

All the ingredients to make an oat crumble topping, weighed out into small bowls.

Apples: You'll need about two pounds of apples. I used Granny Smith because that's my favorite to bake with but you can also use Fuji apples or Honeycrisp apples.
Apple Cider Vinegar: A lot of recipes will use lemon juice, but after watching a Claire Saffitz video on apple pie I loved how she used apple cider vinegar to try and incorporate more apple elements! You can swap it out for lemon juice if you prefer.
Spices: All the warm spices here! I've got cinnamon, nutmeg and cloves. You can also add a pinch of cardamom!
Flour: You'll want to use flour or cornstarch to thicken up the apple pie filling.
Unsalted Butter: I'm using unsalted butter for both the filling and the streusel topping.
Oats: Make sure you use rolled oats or old-fashioned oats. I don't recommend using quick oats, that will make the topping really powdery.

Step by Step Instructions

Streusel in a bowl and cinnamon apples in a bowl.

Step 1: In a large bowl or jug, mix together all of your oat crumble topping ingredients. Smoosh the butter with your hands until the mixture is evenly moist. Place in the fridge and then preheat the oven to 400ºFahrenheit.

Step 2: Peel and slice the apples into half-inch wedges. Place the sliced apples in a large bowl with the spices, vanilla extract, apple cider vinegar, flour, salt, and light brown sugar. Toss until evenly covered.

Step 3: Pour the apple pie filling into your prepared pie dish. This can either be a store-bought pie crust or a homemade one, you just want it to be crimped and very cold!

Step 4: Dot the tablespoon of butter over the apples. Take the oat crumble out of the fridge and sprinkle on top of the pie. Bake in the preheated oven for 20 minutes, then turn the temperature down to 350ºFahrenheit and bake for another 50-60 minutes.

I recommend placing a pie crust shield on the pie after the first 20 minutes. It's ready when the top is brown and you can see the apples bubbling below. Let the pie cool for 3 hours before enjoying!

Expert Tips & Tricks

Apple Slices: Try to make sure your apple slices are the same thickness, that way they cook evenly in the oven and you have tender apples.
Layer the Apple Slices: Instead of just dumping all the apple slices in the pie, I recommend using your hands to layer them so the pie is evenly covered with the slices and there are no large gaps.
Caramel Dutch Apple Pie: Make this a caramel Dutch apple pie by adding a ½ cup of salted caramel sauce to the filling or by just serving with a generous drizzle of salted caramel sauce on top of the baked pie!
Covering the Topping: Keep an eye on the oat crumble topping in the oven. If it's getting too brown you can loosely cover the pie with tin foil.
